Speculation over whether Jessica Simpson is pregnant has run rampant since US Weekly published a cover story in November breaking the big news. (“OMG! SHE’S PREGNANT AGAIN”) Since then, every time Simpson has appeared in public, including as maid of honor at her best friend’s wedding, gossips have examined her belly for signs of life. Yesterday, Simpson confirmed the rumors on Twitter, posting an adorable photo of her 7-month-old daughter Maxwell plopped on the sand above the words “BIG SIS.” The happy news raises just one question: What about that $4 million Weight Watchers contract?

The 5-foot-4 singer and reality star said she weighed at least 170 pounds during her first pregnancy, and that she didn’t worry much about the weight gain. “I thought my doctors were telling me that it was just a lot of water and whenever my water broke my whole entire stomach would go down but that did not happen,” she told Katie Couric. “All the weight did not come out with the baby.” Oh, Jessica. Dear, sweet, innocent Jessica.

But her weight gain did earn her a huge deal with Weight Watchers: $3-$4 million, according to many reports, to serve as the celebrity face of the brand. She signed the deal in May, around the same time she gave birth to Maxwell.

By September, she’d lost more than 40 pounds, and said she was 10 pounds away from her goal weight. But instead of finishing her weight-loss plan and filming a triumphant final commercial, she had to begin hiding her pregnancy until she was ready to share it. US Weekly reported that the company was “livid.” “She was already on thin ice with them since she didn’t lose enough [weight] for the first ad, when they had to shoot her from the waist up,” the magazine said.

Now that it’s out in the open, however, Weight Watchers seems to be sticking by their spokeswoman. She has stopped using the diet, but she’ll keep appearing in ads. “There have been no changes to our business agreement with Jessica,” a Weight Watchers spokesperson told ABCNews.com. “Jessica’s successful weight loss prior to becoming pregnant will be featured in Weight Watchers’ new ‘Expect Amazing’ advertising campaign, including a spot with her sharing the happy news.”

The new ad was posted this morning to YouTube, and features Simpson driving a beat-up old pickup truck into the desert and delivering a simple monologue in which she says Weight Watchers is “built for human nature.” “Being healthy has become a part of who I am,” Simpson says, “which is great timing, because I’m having another baby.”
